  1. Arduino A free development system based on Atmel AVR 8 bit microcontrollers. LB8X Tom

  2. What is AVR • RISC architecture microcontroller • Designed for high level languages, developed in Trondheim, Norway in 1996 • Classic: AT90S1200, AT90S2343, AT90S2313, AT90S4433, AT90S8515, AT90S8535 • ATtiny22, ATtiny25-85, ATtiny2313 ... • ATmega8, ATmega16, ATmega 48-328 ... • Flash programmable memory • ATmega self programming • RAM, EEPROM and peripherals

  3. What is Arduino • Open Source Hardware, you can make your own board, or buy one. • Cheap, easily available. • Open Source Software. • Very widespread, many projects openly available. • Extra HW (shields) available.

  4. Arduino Duemilanove (2009)

  5. Arduino Uno

  6. Arduino Mega 2560

  7. Original Arduino with RS-232

  8. Arduino on breadboard

  9. Arduino Nano

  10. Ardweeny

  11. Arduino IDE

  12. Arduino Language • C like syntax, but simplified • Abstracts the pin naming to numbers • Trades efficience for ease of use • Easy to learn, yet powerful • Lots of example code • Easy to reuse C-code from other projects • Libraries can be written in C++ • Lots of libraries available

  13. int ledPin = 13; // LED connected to digital pin 13 // The setup() method runs once, when the sketch starts void setup() { // initialize the digital pin as an output: pinMode(ledPin, OUTPUT); } // the loop() method runs over and over again, // as long as the Arduino has powervoid loop() { digitalWrite(ledPin, HIGH); // set the LED on delay(500); // wait for half a second digitalWrite(ledPin, LOW); // set the LED off delay(500); // wait for half a second }

  14. BascomAVR IDE

  15. BascomAVR Language • Structured basic • Uses AVR pin naming • Easy to learn, yet powerful • Very efficience, and compact • Can use inline assembly code • Built in simulator • Lots of example code • Must have paid version to make libraries • Lots of libraries available

  16. BascomAVR advantages • Free demo version, up to 4kB code • Supports most AVRs • Commercial version is inexpensive • Excellent support • Active community • Supports bootloaders • Supports many programmers • Can work with AVR Studio
